Create coordination Line -double line?

[k.k]

How do I set up the Create Coordination Line when a double is required?

[MarcLarcher]

Create yourself a double vertical line in the vertical lines tool :

Then it should appear in the Engraving options>Coordination lines :

Not sure whether it’s necessary, I saved my lines as default to have them in all new projects.

Note: my line width is not good, you should choose 1/5 space (as a normal barline) and 1/2 as gap between the lines.

The line will be centered on the existing barline, so you might need to reposition it in Engrave mode, or you’ll get three lines…

Thanks.
